%0 Journal Article %T Logical Analogies: Interpretations, Oppositions, and Probabilism %A Walter Redmond %J - %D 2019 %R https://doi.org/10.3390/philosophies4020013 %X Abstract I present two logical systems to show the ¡°analogy of proportionality¡± common to several interpretations: modality (necessity and possibility), quantification, truth-functional relations, moral attitudes (deontic logic), states of knowledge (epistemic logic), and states of belief (doxastic logic). To display the two underlying analogical relations, I call upon the originally Scholastic convention, recently put to use again, of using squares, hexagons, and octagons ¡°of opposition¡±. A combined epistemic¨Cdeontic logic happens to be found in the traditional ¡°probabilist¡± theory of the ¡°good conscience¡±, and I shall then briefly explain how this is so.
